B20 Residual Chlorine Recorder

Providing permanent chlorine residual records normally means purchasing a residual chlorine water quality monitor and connecting the output of the monitor to a separate recorder. 

ATI’s B20 provides an integrated solution to this problem, combining both the analyzer and recorder functions in a single package. 

This means simpler installation, easier operation, and lower cost. 

And best of all, the system uses our direct measuring membraned sensor for reliable measurement with minimal maintenance.

Series B20 chlorine recorders use the same reliable chlorine sensor supplied for years as part of our Series A15 monitoring systems. 

The sensor is a direct measuring polarographic membraned sensor that eliminates the need for chemical buffers and other reagents. 

Sensors are available for free chlorine measurements or for combined chlorine monitoring where chloramine treatment is in use. 

Chlorine sensors require a constant sample flow past the membrane to provide stable and accurate readings. 

B20 systems are supplied with a constant-head flowcell assembly that automatically maintains the desired flow. 

Hose barbs for sample inlet and drain provide for connection of flexible PVC tubing.
